SPRINGFIELD — Environmental advocates across Illinois are celebrating a major step forward in efforts to protect the state’s remaining wetlands, after the Illinois House Energy and Environment Committee approved House Bill 3596, known as the Wetlands Protection Act.

The committee vote marks a significant milestone for the Protect Illinois Waters Coalition and its partners, who have spent months building support for stronger state-level safeguards. Supporters say the legislation is urgently needed to address gaps in federal protections that have left vast stretches of wetlands vulnerable to development and degradation.

“This is a critical step toward closing a dangerous gap in protections for Illinois wetlands,” said David McEllis of the Environmental Law and Policy Center. “Today’s vote shows lawmakers recognize the urgency of protecting our water, our ecosystems, and our communities.”

Illinois has already lost an estimated 90% of its historic wetlands, according to advocates. More recently, changes at the federal level—including a 2023 U.S. Supreme Court decision narrowing the scope of the Clean Water Act—have further weakened protections. As a result, an estimated 72% of remaining wetlands in Illinois are now at risk.

State Rep. Anna Moeller, the bill’s House sponsor, said the measure is essential to preserving vital natural infrastructure that benefits all residents.

“Clean drinking water, flood protection and other wetland benefits are simply not negotiable,” Moeller said. “They are necessary for all of us.”

The Wetlands Protection Act would establish a state-run permitting program under the Illinois Department of Natural Resources, creating clear, science-based standards to regulate activities such as dredging and filling. Proponents say the goal is to ensure economic development does not come at the expense of environmental health.

Environmental groups emphasize that wetlands play a critical role in preventing flooding, filtering pollutants, and supporting biodiversity. Paul Botts of The Wetlands Initiative noted that without intervention, remaining wetlands could face irreversible damage.

“Wetlands absorb floodwaters, filter pollution, and provide habitat for native species,” Botts said. “Without action, many of these areas are left unprotected.”

The committee approval follows a surge of public engagement, including petitions, testimony, and advocacy efforts at the State Capitol. Supporters say that grassroots momentum will be key as the legislation moves forward.

Advocates now plan to push for swift passage in both chambers, arguing that the future of Illinois’ wetlands—and the communities that depend on them—hangs in the balance.
